UNITED STATES COMBINED GAS-METER AN D GAS-REGULATOR.

SPECIFICATION forming part of Letters Patent No. 573,863, dated December 29, 1.8196.

" Applicaticn filed July 10,1896. Serial No. 598,636. (No model.)

To all whom it may concern:

- ter and Gas-Regulator, of which the following is a'specification.

My invention relates to improvements in a combined gasmeter and regulator; and the objects of my invention are to relieve the constant fluctuating pressure upon the diaphragm of a nieter and at the same time to deliver automatically gas to burners at any desired pressure below that in the street-m ain.

I attain these objects by a combination of.

parts hereinafter described, and illustrated in the drawings, of which-- Figure 1 is a longitudinal section and elevation of the upper portion of a combined gas meter and regulator, showing the imp roveinent. Fig. 2 is a plan view of Fig. 1 with the covers removed.

Similar letters refer to similar parts through out both views. a

A gas-regulator R of any desired pattern or design is shaped in such a manner that it can be inserted and partially fill the open space left in the top chamber of gas met-ers, which is partially occupied by the oscillating levers and the crank actuating the registering apparatus, and the gas-inlet pipe a and the gasoutlet pipe I) are arranged parallel to each other at the bottom of the gas-regulator, and are provided at their lower extremities with flanges by means of which they can be tightly secured to the hollow studs a and 19, projecting from the top of a trough-like closed easting or separatiorrchamber C, which is preferably soldered in a central position to the wall E, separating the lower and upper chamber of a gas-meter G, an openinghaving previously been cut into the wall E corresponding in size exactly with the size of the upper wall 0 of the casting O, and the central portion of the gas-supply channel of the gas-meter having been removed to make place for the body of this separation-chamber C.

The ends of the chamber 0 are provided with openings f and g, into which the two sections 3 s of the gas-supply pipe of the gasmeter are secured, preferably by the solder-' ing process. Half-way between the studs 0. and b and parallel to the end walls a central partition D is provided in the separationchamber 0, as shown in Fig. 1 of the drawings.

The open top R of the gas-regulator R, which for constructive reasons is preferably shaped like a hollow semicylinder, slightly projects beyond the top cover G of the gasmeter, to which it is firmly secured by soldering, and is provided with a removable cover having a protected opening it for the ad mission of the air.

The proceedings in fitting the apparatus are then as follows: The east-ing 0 having been soldered to the wall E of the gas-meter in a position described above and shown in the drawings, and the ends of the broken gassupply pipe 8 8 having been secured thereto in the manner described, the gas-regulator is attached thereto by securing the flanged ends of the pipes at and b, respectively, to the studs a and Z) by means of the screw-threaded nuts a 73 as shown in Fig. 1 of the drawings. The levers are then connected and the cover G of the gas-meter is slipped over the top R of the gas-regulator, and the cover G is then made air-tight by soldering it to the body ofthe meter and around the semicylindrieal opening to the top R of the gas-regulator, and the apparatus is ready for work.

The gas will pass from the supply-pipe S into one side of the separation-chamber (J, and from there through the pipe 0. into the gasregulator R. It will leave this regulator at a reduced pressure through the pipe I) and pass to the other side of the chamber C and from there through the pipe 5 into and through the gas-meter G. Thus the bellows of the gas-meter will be actuated by an equal reduced pressure considerably less than the pressure in the 4 street-main, and the life of a gas-meter, or the time which it is capable of serving, will be greatly prolonged, causing a great saving of expense, while the feature of a smooth regular gas-supply to the. burners is preserved without requiring extra space and additional pipe-fittings.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

IOO

a gas-meter easing G having a separationwall E with a chamber O having the studs (1 and b, a gas-supply pipe 3 and a cover G having a selnioylindrieal opening, in combination with a gasregulator R having below the parallel gas-cluets a and Z) and the nuts 0 and b and above a hollow semieylinclrioal projection R provided with an air-hole h as I11 acombinedgas-nieterancl gas-regulator, and for the purposes herein shown and set 10 fort/h.

Signed at New York, in the county of New York and State of New York, this 8th day of July, A. D. 1896.
